Specification forming part of Letters Patent No. 210,855, dated December17, 1878 application filed March 29, 1878.

To all whom it may concern:

Be it known that I, DEMn'rRIUs J ANNO- PonLo, of the city of St. Louis,and State of Missouri, have invented certain new and useful Improvementsin Pulleys for Awnings; and I do hereby declare that the following is afull, clear, and exact description thereof, which will enable othersskilled in the art to which it appertains to make and use the same,reference being bad to the accompanying drawings, and to letters ofreference marked thereon, which form a part of this specification.

My invention refers to an improved pulley for the lowering or raising ofstore or other awnings.

The use of glass eyelets or rings for this purpose where manyelevating-cords are required continually expose the cloth to being drawninto the eyelet with the cord, thus causing the passage of the cord tobe stopped by jamming or a frictional burning of holes in the cloth. Toprovide a better device, I make a metallic swivel pulley which perfectlyprotects the cloth, and is also a reliever of friction, and alsoobviates entanglement of the cords and sagging together.

A twenty-foot awning requires five to six cords with which to raise orlower it. The device which I have provided is a pulley of peculiarconstruction. Its frame is adapted to the reception of several sheavesin a tier, and one or more tiers in depth, each sheave in each tier being separated from its adjunct by a rounded bar in the metallic frame, toprevent the chafing of the cords. To the pulley is formed a swivel-head.On the upper end I cast a swivel-plate, having a slot, into which theswivel-shank can enter, and which allows a perfect swivel action to thepulley. The attachment of this swivel-plate is for overhead suspension,particularly when the draft and weight points are at adverse angles.

In the accompanying drawings, Figure 1 is a skeleton perspective of anawning-frame, which shows the manner of application of my improvedpulley. Fig. 2 is an enlarged perspective view of the pulley, withreference to the general manner of its attachment to a facing, and theentrance'slot for the swivel-neck.

Specifically described, the facing A may be a long piece of 3x 2 stuff,and be spiked to the wall G or a projecting mantel, A, to protect thefolded awning. The awning-pole B may be attached to the hingedextension-rods E by the screws and nuts b. The said extensionrods areattached to the house-front by hinged jaw-plates G D. The hoisting andlowering cords 0 pass, respectively, from the said awning-pole B overthe said pulley F, the more distant cords being intermediately supportedto the point from which they are led down to the belaying-pins.

The pulley-frame i may be so cast as to vary in the number of tiers andsheaves, since a single sheave serves for the most distant cord.

It will be observed that the said pulleyframe i prevents the drawing ofthe awningeloth into the sheaves.

The hanging plate H has passing beyond If DEMETRIUS J ANN OP OULO.
